This can be reproduced with nvidia and intel drivers.
Also user was running custom build xcompmgr 1.1.9.
When testing with EPEL8 xcompmgr 1.1.8 the issue can also be reproduced.
There are no specific steps to reproduce.
Quoting user:
We did some tests with both the screensaver and DPMS and could not make it crash by simply enabling/disabling these features. We also tried xcompmgr-1.1.8-2.el8.x86_64.rpm and picom-9.1-1.el8.x86_64.rpm; in both cases we go the same Xorg core file.
